Careland Ultrasonic Pest Repeller Squirrel Repellent, 4 in 1 Rodent Repellent Plug-in Mouse Deterrent Emits Ultrasound Waves and LED Strobe Lights Indoor Use

I ordered a 2 pack. What I received 1 single item. No explanation or partial refund.Update: The seller promptly contacted me and explained the issue and offered either a replacement or partial refund. I opted for the replacement. The additional item was received quickly.Have been using these for a couple weeks. Initially the activity increased as expected, now the activity is significantly less. I would recommend these for people looking for a non-toxic alternative that is safe to use around pets

The main feature is that it sounds a "clicking" noise to irritate the rodents. There's also a bright flashing light. The only part of it that works past three months is the very loud siren setting which I can hear inside my house - the item is in a detached garage 100 ft. away from the house. The clicker stopped within a week. The light worked for a bit longer.

I thought it was going to be two products but only received one item. Because in the picture there is two products.
